Post 16 - Experiments
I spent the day trying out techniques for the upcoming parts of my build. Started off trying out different methods of blackening. First up was Liver of Sulfur - so named because the dried compound has the color of fresh liver. I had read it is less toxic than other blackening agents, and will not affect painted parts. I diluted it as directed, and set up a work station with 3 small bowls: the LoS, baking soda dissolved in water to neutralize it, and plain water to rinse. I washed the blocks and their attached hooks in Dawn, and wore exam gloves. In goes the first piece, and nothing happens. Made the LoS solution stronger, still nothing. I got out my Jax Pewter Black, and still nothing. It finally dawned on me that the copper wire was coated with something. At that point the rotten-egg aroma of the Liver of Sulfur was getting to me, even in a garage with both doors open. I decided I would stick to the Jax, which has no smell.
I took a piece of the wire, ran it through some sand paper, and put it in the Jax - Voila! So I removed and remade my hooks using roughed-up wire. They actually turned out better than my first attempts. I did a little more reading about Jax. The online consensus is that diluting it about 50:50 with water is best, and brushing it on is somehow better than dunking pieces. Also, if you do dip it, after it first darkens you should remove the piece, give it a wipe to remove the loose black crud that can form on the surface, and then redunk. That may be why painting works better - you remove the crud with the brush strokes. I had painted an extra Syren resin block, so I wrapped a piece of wire on the strop and put it in the Jax to see what would happen to the paint and resin. The answer is nothing, and the wire darkened nicely.
I held the blocks in one hand and applied the Jax with a brush. Each one took a few minute to darken. I finished off by giving them a quick dunk in the solution. Luckily, my 28g wire arrived today (which does not have a coating) so I could also do my smaller blocks for the jib halyard and downhaul.
This time, the blackening did not instantly rub off, as had happened when I used full strength on my eyelets. I went ahead and blackened the hanks for the jib while I was at it.
I'm using the Model Shipways 0.4mm line for my mainsail halyards. My goto YouTube modeler, HillBilly Modeler, suggested boiling the line for 3 minutes to remove the kinks. I measured the length I need for the throat halyard, boiled away, then put a self closing tweezer at each end and hung it off a table to stretch it while it dried. No kinks!
I tried making a "false glued eye splice" as kind-of described in the plans, but couldn't get it to work with PVA glue. I ended up forming a small eye and using CA glue where the line crossed itself, I then trimmed it and tried to shape with my fingers it before the glue set. It worked, but not great. I used it to rig the throat halyard.
I bought a Syren Rope Serving Machine in anticipation of the bigger builds in my stash. I decided to experiment with that on the peak halyard. I jerry rigged an alligator clip to it to hold the block. I looped the line though the strop, fixed a loop with a half hitch touched with CA glue, and then used one end of the half hitch to wrap the line 4-5 times to simulate the thickness of a splice. It looks pretty good, and fells more secure than my glue only attempt.
The only other things I can do until my dark brown line arrives is attach the halyard, downhaul and jib sheets to the jib. A good day of testing new things. I'm particularly glad that I figured out the alchemy of blackening, and that I can use Jax Pewter Black on wires already attached to blocks!
